Application July 16, 1942, Serial No. 451,199

4 Claims.

male and the other end female and also in which scription following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:

Figure 1 is a central longitudinal sectional view 7 through a cartridge and portions of others, ac-- cording to my invention;

Figure 2 is a side elevation of a cartridge constructed in accordance with the invention;

Figures 3 and 4 are end views of the cartridge, the latter showing a stud in place;

Figure 5 is an elevation of one of the end discs;

Figure 6 is an elevation of one of the connecting studs, and

Figure 7 is an end elevation of a modified form of washer.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, each cartridge consists of a tubular casing 10, usually of paper, containing an explosive charge I I which is held in place by heavy paper discs l2 located inwardly of the ends of the casing l0.

Mounted in the ends of the casing in of each of the cartridges are non-ferrous washers l3 which preferably have a marginal flange 14 around their outer edges. Washers i3 have central screw-threaded openings at I5 which are adapted for screw-engagement with studs l6, also of non-ferrous metal. The washers I 3 and I6 are preferably of non-ferrous metal like brass but they may be made of plastics, indurated fiber or otherwise.

It will be noted that the ends of the casings ID are inwardly crimped over the flanges M as at IT.

I thus provide a unit as shown in Figure 2, which is female at one end and male at the other end since at the first end, one of the openings or washers I3 is devoid of a stud while the other washer has a stud extendin therefrom. The

cartridges or units may thus be readily connected together by screwing the male or stud end into the other ends to make up an explosive cartridge of any desired length and capacity. Attention is called to the fact that the discs H! are capable of slightly sliding or yielding within the casing l0 and that th washers l3 are also capable of slight sliding or yielding. As a resultjwhen the parts are screwed or connected together, with the casings crimped inwardly at H, all of the strain is placed on the casing.

According to the sensitivity of the explosives H, the studs l6 are made solid as in Figure 6 or hollow as at 18 in Figure 1, and the washers 13 may be perforated to the extent desired as at 19 in Figure 7.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. An explosive cartridge having a tubular casing, washers disposed in the opposite ends of said casing, the terminals of the casing being extended inwardly over said washers, said washers having central openings provided with screwthreads, and stud means detachably engaging the screw threads whereby the washers may be connected to corresponding washers of adjacent cartridges.

2. An explosive cartridge having a tubular casing, washers disposed in the opposite ends of said casing, the terminals of the casing being extended inwardly over said washers, said washers having central openings provided with screwthreads, and stud means detachably screwthreaded, to corresponding washers of adjacent cartridges, said washers being perforated.

3. An explosive cartridge having a tubular casing, washers disposed in the opposite ends of said casing, the terminals of the casing being extended inwardly over said washers, said washers having central openings provided with screwthreads, and stud means detachably screwthreaded to corresponding washers of adjacent cartridges, said stud means being hollow.

4. An explosive cartridge having a tubular casing, washers disposed in the opposite ends of said casing, the terminals of the casing being extended inwardly over said washers, said washers having central openings provided with screwthreads for detachable engagement with screwthreaded stud means whereby the washers may be connected to corresponding washers of adjacent cartridges, said casing being of paper, and discs within the casing engaged by the washers,

and said washers and stud means being of nonferrous material.
